  • Method of cutting metal pipe and its apparatus
    Patent number: 6357327
    Abstract: An apparatus is provided for cutting a resin-coated metal pipe. The apparatus includes first and second spaced apart pairs of holding members for holding the pipe. First and second cut-off blades are movable between the pairs of holding members for making substantially diametrically opposed pre-cuts in the pipe. The cutting members move substantially in the same tangential direction to substantially balance rotational forces on the pipe. A cut blade then is penetrated through the pipe from the one pre-cut to the other to provide a clean precise cut in the pipe.
